Question

Which of the following methods is the best way to compare the lengths of two line segments?

• A. None of these
• B. Comparison using a ruler and divider
• C. Comparison by tracing, using a tracing paper
• D. Comparison by observation

Answer 1

The correct option is B

Comparison using a ruler and divider

The best method to compare the lengths of two line segments is by using a ruler and divider. Keeping the two needles of the divider at the ends of a line segment, and then placing it besides a ruler gives the most accurate measurement of the line segment, provided that the divider's arms are not disturbed in the process once they've been fixed at the ends of the line segment.
